Satchmo: the differences are largely in the thickness of the "wood" layer. Get the thickest layer possible for the money. Easy to install, though don't forget to work in the price of a layer of thin foam or similar material as suggested in the installation instructions. When you tap the laminate into place, I suggest you use your first off-cut and insert it into the groove of the wood you're tapping into place. Both tongue and groove are easily damaged by direct tapping.
